98a3911c43 py/scheduler: Add "raise_exc" argument to mp_handle_pending.
Previous behaviour is when this argument is set to "true", in which case
the function will raise any pending exception.  Setting it to "false" will
cancel any pending exception.

2c8c2b935e stm32/powerctrl: Improve support for changing system freq on H7 MCUs.
This commit improves pllvalues.py to generate PLL values for H7 MCUs that
are valid (VCO in and out are in range) and extend for the entire range of
SYSCLK values up to 400MHz (up to 480MHz is currently unsupported).

96a4435be1 stm32/boards/STM32F769DISC: Add config to use external SPI as filesys.
This board now has the following 3 build configurations:
- mboot + external QSPI in XIP mode + internal filesystem
- mboot + external QSPI with filesystem (the default)
- no mboot + external QSPI with filesystem

30501d3f54 drivers, stm32: Support SPI/QSPI flash chips over 16MB.
With a SPI flash that has more than 16MB, 32-bit addressing is required
rather than the standard 24-bit.  This commit adds support for 32-bit
addressing so that the SPI flash commands (read/write/erase) are selected
automatically depending on the size of the address being used at each
operation.

b72cb0ca1b py/mpthread.h: Use strong type for mp_thread_set_state() argument.
This modifies the signature of mp_thread_set_state() to use
mp_state_thread_t* instead of void*.  This matches the return type of
mp_thread_get_state(), which returns the same value.

`struct _mp_state_thread_t;` had to be moved before
`#include <mpthreadport.h>` since the stm32 port uses it in its
mpthreadport.h file.

a542c6d7e0 stm32/powerctrl: For F7, allow PLLM!=HSE when setting PLLSAI to 48MHz.
PLLM is shared among all PLL blocks on F7 MCUs, and this calculation to
configure PLLSAI to have 48MHz on the P output previously assumed that PLLM
is equal to HSE (eg PLLM=25 for HSE=25MHz).  This commit relaxes this
assumption to allow other values of PLLM.

bfbd94401d py: Make mp_obj_get_type() return a const ptr to mp_obj_type_t.
Most types are in rodata/ROM, and mp_obj_base_t.type is a constant pointer,
so enforce this const-ness throughout the code base.  If a type ever needs
to be modified (eg a user type) then a simple cast can be used.

e3187b052f stm32/boards/PYBD: Change RTC asynch prediv from 1 to 4.
This change has the following effects:
- Reduces the resolution of the RTC sub-second counter from 30.52us to
  122.07us.
- Allows RTC.calibration() to now support positive values (as well as
  negative values).
- Reduces VBAT current consumption in standby mode by a small amount.

For general purpose use 122us resolution of the sub-second counter is
good enough, and the benefits of full range calibration and minor reduction
in VBAT consumption are worth the change.

4c93955b7b py/objslice: Add support for indices() method on slice objects.
Instances of the slice class are passed to __getitem__() on objects when
the user indexes them with a slice.  In practice the majority of the time
(other than passing it on untouched) is to work out what the slice means in
the context of an array dimension of a particular length.  Since Python 2.3
there has been a method on the slice class, indices(), that takes a
dimension length and returns the real start, stop and step, accounting for
missing or negative values in the slice spec.  This commit implements such
a indices() method on the slice class.

It is configurable at compile-time via MICROPY_PY_BUILTINS_SLICE_INDICES,
disabled by default, enabled on unix, stm32 and esp32 ports.

This commit also adds new tests for slice indices and for slicing unicode
strings.

61d2b40ad5 lib/utils/pyexec: Introduce MICROPY_REPL_INFO, wrap debug prints in it.
For the 3 ports that already make use of this feature (stm32, nrf and
teensy) this doesn't make any difference, it just allows to disable it from
now on.

For other ports that use pyexec, this decreases code size because the debug
printing code is dead (it can't be enabled) but the compiler can't deduce
that, so code is still emitted.

93509ac8c7 stm32: Add configuration to build in nanbox mode.
Most stm32 boards can now be built in nan-boxing mode via:

    $ make NANBOX=1

Also, native emitters will be disabled.

- Removed remarks on DFU/OCD in mpconfigboard.h because deploy-stlink works
  fine too.
- Added more UARTs, I2C, corrected SPI, CAN, etc; verified against CubeMX.
- Adapted pins.csv to remove errors, add omissions, etc. according to
  NUCLEO-144 User Manual.
- Changed linker file stm32f767.ld to reflect correct size of the Flash.
- Tested with LAN and SD card.

40cc7ec677 stm32/mpconfigport.h: Use IRQ_PRI_PENDSV to protect bluetooth ringbuf.
The default protection for the BLE ringbuf is to use
MICROPY_BEGIN_ATOMIC_SECTION, which disables all interrupts. On stm32 it
only needs to disable the lowest priority IRQ, pendsv, because that's the
IRQ level at which the BLE stack is driven.

certain length.  Such objects also support the extended block protocol.
The signature for the constructor is: pyb.Flash(start=-1, len=-1).

7723dac337 stm32: Generalise flash mounting code so it supports arbitrary FS.
This commit refactors and generalises the boot-mount routine on stm32 so
that it can mount filesystems of arbitrary type.  That is, it no longer
assumes that the filesystem is FAT.  It does this by using mp_vfs_mount()
which does auto-detection of the filesystem type.
